Quantum Power Flow

open access: yesIEEE Transactions on Power Systems, 2021
This letter is a proof of concept for quantum power flow (QPF) algorithms which underpin various unprecedentedly efficient power system analytics exploiting quantum computing. Our contributions are three-fold: 1) Establish a quantum-state-based fast decoupled model empowered by Hermitian and constant Jacobian matrices; 2) Devise an enhanced Harrow ...

Optimal Power Flow Control by Rotary Power Flow Controller

open access: yesAdvances in Electrical and Computer Engineering, 2011
This paper presents a new power flow model for rotary power flow controller (RPFC). RPFC injects a series voltage into the transmission line and provides series compensation and phase shifting simultaneously. Therefore, it is able to control the transmission line impedance and the active power flow through it.
